A-Level Chemistry Tuition
Is A-Level Chemistry jeopardising their university offer?
For high-achievers, chemistry is often the make-or-break subject. I specialise in turning the ‘maximum effort, minimal results’ paradox into the A/A* grades required for competitive courses like Medicine, Dentistry, and Engineering
IB Diploma Chemistry Tuition
When the pressure of IB crushes both grades and wellbeing.
The immense pressure of the IB Diploma can take a serious toll. I provide the expert strategy to navigate unpredictable exams and the complex IA, transforming overwhelming stress into the high-scoring results your child’s hard work deserves
GCSE & IGCSE Chemistry Tuition
Feeling lost in a mountain of content?
It’s frustrating when hours of work don’t lead to better mock results.
I transform confusion into clarity and confidence, building a rock-solid foundation that makes top grades achievable and future A-Levels / IB Diploma far less daunting.
Meet Your Tutor, Dr Carl Thirsk
As a PhD chemist, published author, and full-time educator, I have dedicated over 14,000 hours to one-to-one tuition, helping students achieve exceptional results.
My structured, evidence-based approach consistently helps 94% of my A-Level and IB students secure the top A/A* or 6/7 grades.
My background as a former R&D CEO and my work as an examiner gives me a unique perspective, allowing me to build not just knowledge, but the real-world problem-solving skills students need to excel.

What Parents and Students Say
“Carl’s expertise was instrumental in her success…she’s off to study medicine at Newcastle”
“My daughter was struggling with a lot of the more complex calculations and 2nd year content, which was holding her back from reaching her true potential and target grades. Carl’s expertise was instrumental in her success in A-Level Chemistry – he provided the precise, targeted support she needed. She’s off to study medicine at Newcastle. We couldn’t be more pleased with the outcome and the quality of the tuition.”
Dr. Sarah W., parent of A-Level Chemistry student, AQA (Summer 2025)
“I honestly can’t believe I got a 7!”
“I honestly can’t believe I got a 7 in IB Chemistry! I was really struggling with a lot of Reactivity 3 (especially redox and pH calculations) and some of the HL bonding but Dr Carl’s lessons made everything so clear and manageable.
The question packs he shared to help with the new spec were amazing and made such a difference as well. Thank you so much!”
Emma R., IB Chemistry student, International Baccalaureate (May 2025)
“Our son exceeded our expectations and his initial mock results.”
“Our son found topics like acids and bases and redox (electrolysis) to be a challenging topic and was not performing well on it despite putting in the work. We reached out to Dr Carl for help and were so impressed by his approach. Thanks to his focused lessons, our son exceeded our expectations and his initial mock results. We are so pleased he got the grade he needed and deserved for college.[Note: Final grade was an A, well done!]”
